Multiple connection slows network access

I have a AP1252AG with a 5Ghz and a 2.4Ghz radio installed on it.
It is connected to a Gig port on my Cisco 3750.
The Dell Vostro 1720 has a 802.11n wireless adapter.
I go the the 1252 configured to run 802.11n per a cisco document I got off the internet.
I can connect with one laptop at 300Mbps and then drop down to 81Mbps and then back up to 300Mbps again.
When I bring in multiple same type laptops my response time drops to and the application they are running comes to a crawl
They are all running an application that is on a local server attached via gig port on a cisco 6509.
We had planned on having up to 10 laptops using this single 1252. Is that expecting to much through put capablility to support.
Is there 1252 radio configuration setting that will provide the best throught put for 802.11n connection?
Is there a 3750 gig port configuration that would provided the best thought put with a WAP attached.
Thanks
Ken

I have done further research into my problem by reading other discussions with my same problem.
I am now able to connect at 130Mbps max with my Dell Vostro. In the other discussions they talk
about setting the default Guard Interval from 800NS to short 400NS to get to 144 Mbps and then set
the 5Ghz radio to double width channel to ge 40Mhz channels to get 300Mbps. How can I do this
with a 1252 stand-alone using gui interface configuration. If there is only command line configuration
to do this, what is that?
Thanks
Ken

, new laptop just got it today, not sure what this is, I can get online but it's slow, I have been trying to fix this for the past 3 hours, help please, I am not tech savy.

Hi DawnAngelique,
In addition to carey , please check your LAN connection and network state .
If the issue persists I would suggest you to update driver for your network adapter then check the result .
Please feel free to let us know the further progress .

Time machine running slow and slowing network access

I have had and continue to have issues with wifi on my MBP. Those are pretty well summarized in https://discussions.apple.com/thread/5535320?start=30&tstart=0. I've been able to make mt system usable with some of the less dodgy workarounds in that thread ( like keeping a ping on my router running )
That thread really doesn't mention the issues I've been having with time machine though, so I thought I'd bring this up here. Whenever time machine starts up, Safari and mail become unresponsive. It's worst when TM is "preparing" of "cleaningup", though barely usable during the actual backup. Mostly, I can work around that too, but occationally, TM will find GB of data to be backed up and lock up my mac for a day. Here's a recent example:

This is on an AC router. My peak throughput shows 19 Mb/s on menu meters, so, not great, but not this slow. Mostly, the network activity is nothing with short bursts of higher throughput.
I'm hoping this will be addressed in 10.9.2. In the mean time, are there any workarounds to get past this issue short of turning off TM?
Thanks,
Horst

These instructions were taken from Mac OS X Hints at:
http://hints.macworld.com/article.php?story=20050302225659382
The Unix program dd is a disk copying util that you can use at the command line in order to make a disk image. It makes a bit-by-bit copy of the drive it's copying, caring nothing about filesystem type, files, or anything else. It's a great way to workaround the need for Norton Ghost.
Normally, in order to make a disk image, the disk you're copying from has to be able to spin up and talk -- in other words, it's OK to make a copy if the disk is healthy. But what happens when your disk is becoming a doorstop? As long as it continues to spin, even with physical damage on the drive, dd and Mac OS X will get you out of the fire.
We had a situation recently where a friend sent a disk to us that had hard physical errors on it. It would boot in Windows, but then it would hit one of these scratch marks and just die. We fired up dd, and it started OK, but stopped at the same physical error location -- complaining about a Hard Error.
So the workaround was to designate the dd mode as noerror -- which just slides over the hard stops, and to add the mode sync, which fills the image with nulls at that point. We did it on BSD Unix, but as long as you can get the hard drive attached to your Mac, the command is the same:
dd bs=512 if=/dev/rXX# of=/some_dir/foo.dmg conv=noerror,sync
The bs=512 designates block size, and the if=/dev/rXX# is the UNIX path to the actual disk device. Make sure that the chosen directory (some_dir) has enough room to take the entire disk image -- which will be equal to the size of the drive. Since dd doesn't care about the contents of the drive, it copies every bit on the thing, so you get an image equal to the disk's capacity. A really big file. One workaround is to put it on a RAID array.
Once you've established the disk image (in this example, foo.dmg), you're almost home. Here's where your Mac OS X box is far and away the best thing to have. In this example, the dd output file is foo.dmg. You have to realize that this is an exact copy of a busted drive, but the "holes" are filled with nulls. As long as the damage isn't to the boot sector, though, when you double-click on it, Mac OS X mounts it without breathing hard ... who cares if it's FAT32, NTFS, whatever.
Due to the size of the image that we were copying, we put it on a RAID array, and had to access the image over the network -- it still mounted fine. In straight UNIX, if you try to mount a disk image, it complains that there is "no block device" and fails. Once your image is mounted, it appears in your Finder, and then it's easy work to retrieve the critical files from the image -- usually things like .doc files and .xls files and the lot.
Finally, since your disk is actually dying, once you have your image, you can drop it to tape or something and you've not only recovered your files, you've made a viable backup as well. Once again, that which destroys a Windows box becomes a play thing to a Mac OS X box.

Slow Network Access After Update to 10.5.4

Hello all. i updated my macbook from 10.5.3 to 10.5.4 some time ago and as soon as i did that, all my network shares take several seconds to connect now. each time i connect to them takes a pretty long time. i am now on 10.5.5 and this is still occuring. it was VERY snappy in 10.5.3, almost no time to connect to a share, specifically a windows smb server. the server runs fine from other computers and no errors are logged on either the server or the macbook. the macbook does connect and once connected it is pretty fast moving around in folders and copying but the initial connection is just so slow since this update. i cant find any info regarding this particular issue anywhere. any suggestions? thank you!

thank you for the suggestion. it ended up that i had vmware fusion 2.0 on my system and the extra virutal nics, vmnet1 and vmnet8 were causing it. i commented out all their entries in the locations file and rebooted. it works normally now.

Very Slow Network access for some computers

This has me baffled, I'll try my best to explain.
We have an xserve g5 conected to xserve RAID, the xserve has gigabit ethernet.
All Client computers are also on Gigabit ethernet.
Users are all on network homes on the Server.
Most users are getting descent speeds, transfering a file from the RAID to their (network) desktop takes around 40 seconds for a 1Gb file.
However two users noticed transfer was much slower, 20 mins for the same file.
I've ruled out cable problems and hardware problems because if I transfer to the local computer harddrive the speed is up to around 1 minute.
But I've also ruled out a problem with the user account, because if the same user logs onto another mac the speeds are around 40 seconds.
I tried logging other users into the problem macs and all users drop to 20 minutes.
The only thing I can thing it could be is some problem with how those computers are binding with the server, I tried unbinding and resetting up directory access but that made no difference.
What else can I try other than re-installing?

I went ahead and did a fresh install, but this did NOT fix the problem.. I really can't think what else I can do!
Noticed in Network utility there are a lot of received errors when copying a file.
I replaced all the cables but again I don't think its can be a hardware problem because transfer rates are fine from local harddrive to server, but very slow between 2 network disks (unusually slow, considering all other computers are fast transfering the same file to the same place) HELP!

A solution to no network access in guest OS

Hi.
Host OS: Windows Server 2008 R2 / Hyper-V
Guest OS: Windows Server 2008 R2
Had a problem with "no network access" in guest OS.
However, as many others could not get rid of the Virtual Network card in Device Manager (which also seems to manage the LAN Connection object under Network and Sharing Center > Change Adapter Settings)
After a few hours this seems something like what you need to do to get rid of the faulting Microsoft Virtual Machine Bus Network Adapter ... so the Guest OS can automatically reinstall it. These steps worked for me:
Probable Prerequisites:
0)
- The host OS runs the Virtual Network Switch on one of the physical network adapters or on the same adapter (if there is only one). In my case I run on the 2nd physical adapter.
- Hyper-V Virtual Network manager has a virtual network on one of those adapters.
- The VM with the guest OS is bound to the virtual network
1) Event log > System probably has an event saying something is wrong with the Microsoft Virtual Machine Bus Network Adapter and you need to reinstall it (but how!!!)
Fix Guest OS LAN Connection:
1.a) Hyper-V Manager Actions:
Hyper-V Manager > Shutdown or turn off the Guest OS in
Hyper-V Manager > VM Guest OS > Settings > Network Adapter remove
1.b) Hyper-V Manager VM GUest OS States:
{ No network adapter available for guest OS }
2.a) Hyper-V Manager Actions:
Hyper-V Manager > VM > Start VM Guest OS
2.b) Guest OS States:
{ DM > Virutal network card and Network and Sharing Center > Connection LAN is strangely still available even though the virtual network adapter hardware was removed in step 1 }
3.a) Guest OS Actions:
Go to Network and Sharing Center > Change Adapter Settings > "LAN Connection" object > Properties
Click every protocol etc. and click the uninstall button
3.b) Guest OS States:
{ The LAN Connection object is gone under Network and Sharing Center }
{ The Network card is gone under Computer Administration > Device Manager }
4.a) Guest OS Actions:
cmd > Run as Administrator >
set devmgr_show_nonpresent_devices=1
devmgmt
In device manager goto the network node and uninstall all references to Microsoft Virtual Machine Bus Network Adapter
(In my case I used the guest os for a Windows Backup sysrecovery because of changes in the disk layout thus I also had some additional references now visible to the previous physical network adapters and uninstalled them as well)
4.b) Guest OS states:
{ Device Manager > Microsoft Virtual Machine Bus Network Adapter not present }
5.a) Hyper-V Manager Actions
Shutdown VM Guest OS
VM Guest OS > Settings > Add Virtual network adapter for external network
Start VM Guest OS
5.b) Guest OS States:
{ Guest OS ready for plug and play installation of Microsoft Virtual Machine Bus Network Adapter }
{ Device Manager > Network Adapters > Microsoft Virtual Machine Bus Network Adapter is installed and activated }
{ Network and Sharing Center > Connection LAN object is installed and activated }
{ LAN is connected with network access through the Virtual Network switch in the Host OS }

Thank you for the post. After searching for weeks on end and trying all kinds of solutions, I was finally able to resolve the issue by removing the "Microsoft Virtual Machine Bus" from the Guest machine on Hyper-V.
No matter what change I was applying I kept getting the "169" based IP.
My host system is "Windows 8.1 Pro" with Hyper-V role enabled and my guest machine is "Windows 8 Enterprise". I was starting to question if it's the enterprise machine that may be an issue, but glad this is resolved.
Thank you for the solution.

following instructions of bluetooth guide i installed transrecieving key in Acer system, also i installed winroute lite configured it as per guide & also configured the blue tooth server adapter @192.168.1.1 in network properties & subnet @255.255.255.0.
I have instaleld bluetooth bracket & antenna & set up that MSI board based system as client.
both the pcs are able to discover eachother
all the services are running by automatic means .
I attempt to connect using network access using my msi based system. evey time i get the same response that :connection could not be completed or error connecting to (the name of other computer)
i have disabled all the authentication authorisation & encryption at all levels.

also i enabled acces using dial up server window on server pc using transrecieving key i made it allow called access s & also disabled require encrypted password & made the server type as ppp windows 98 server.
after that i did it viceversa i.e i made the msi based based board the server pc & acer system aas client still afer initiating & discovering the services i try to connect & get the same error messages.
I am in complete mess.
please help!!

Depend the model of your Mac doesn't work, I have iPhone 6 iMac mid 2011 and MacPro 2012 and doesn't work, the problem is the version of Bluetooth, you must have a Mac from mid 2012 or version bluetooth 4.0

MS Access connectivity gets slow when connecting insidde network domain

Hello,<o:p></o:p>
We've created an application based on Excel VBA that connects to an access DB located at the file server in our network domain. Now I'm installing
same app in another server for another domain, but the connection is really slow so the app hangs while retrieving information from the .mdb file located at the server.<o:p></o:p>
I created a local environment in my computer to test and realized as as soon as I connect the network cable the connection to the DB get slow, but
when I unplug the network cable the app start to responding as usual.<o:p></o:p>
I'm using Ole DB jet 4.0 with the following connection string:<o:p></o:p>
cnt.Open "Provider=Microsoft.Jet.OLEDB.4.0;Data Source= MasterDB ;Jet OLEDB:Database Password= 12345;"<o:p></o:p>
It seems that the problem it is related to some authentication on the server that makes the connectivity slow because it has not sense to me that
when I connect the network cable and log into the domain the speed goes down even if the application is looking to the DB file in mi local hard drive.<o:p></o:p>

I'd try them over here.

Painfully slow network connection

I am trying to evaluate the prospect of installing OS X Server 10.5 on a G5 tower at my workplace, and one of the primary issues is the speed of the office network. Perhaps due to the fact that we are physically located in two different buildings, we not infrequently have problems with some computers connecting to the server (currently running OS X 10.4 [Client]). When connecting via AFP, for example, some computers time out trying to connect or grind to a halt trying to open or save a Word document or something. The server also tries to back up all of our machines using Retrospect, and while some computers transfer files at around 100Kbps, some are around 2K or, again, just time out.
I'm trying to get the network folks to look into these issues, but my basic question is this: if I want to have people able to log in and use their home directory on any computer, can I set things up such that if a given computer has a terribly slow connection to the internet, they can at least login to some local account instead? Ideally, if on their own computer, the fallback would be a cached copy of their own home directory, a la Portable Home Directories. I'd probably be happy with just a vanilla account, though.
In the same vein, if someone logs in using their network home directory, but the network connection goes to ****, will they be unable to do anything? Will they at least be able to log out and switch to a local account? I suppose that this would only work if each computer archived a copy of the user account of any user that logged in using it.
Thanks for any advice you have on implementing this sort of scheme,
Greg

{quote}With the AirPort Extreme, in the AirPort panel, Wireless tab, click on the button for "Wireless Network Options", check the box for "5 GHz Network Name", and enter a different network name. (That can be trivially different, such as the name of the main network suffixed with an underscore and the digit 5.) Once configured that way, connect your "N" gear to each network in turn to see if one is any better than the other. (If you're wondering what effect this would have, it allows segregating your "N" gear from the older gear to prevent the older gear from slowing down your network. However, distance and interference from things like walls may negate any advantage.){quote}
William: I was gone most of yesterday, but had a chance to implement your recommendations today. I added the 5 GHz network as you suggested, but in order to connect to that at all with my 802.n11 MacBokk Pro, I need to be within a few feet of the AE (base station). If I try to access that network even from the next room (well within reach of both the AE and the livingroom AX, I get one bar and "failure to connect" messages just trying to logon to that network.
However, I did some experimenting that (as of right now, anyway) resulted in much faster network access, not only from my MacBook, but also from the older iMac which is the furthest Mac from the AE. According to my wife, that iMac is "loading web pages faster than I've ever seen them!"
Here's what I did:
1. Moved all three units to places where it seemed they would have the least amount of interference with the clearest path from unit to unit, also raising the height of both AXs from about 2-3 feet from the floor to about 5-6 feet from the floor.
2. Changed one setting on the AE (base station): Wireless Tab > Wireless Network Options > Multicast Rate ---> Changed this from Low to High.
I have a feeling the location shifts made the real difference, but I will try changing the multicast rate back to "Low" just to see what happens.

Slow database access across network

I have a postgresql database setup on a server machine and have written a java program in netbeans that accesses it. The problem i have is that running the jar created by netbeans from any other machine on the network has really slow database access but running the program from netbeans itself is fine. Running the jar on the server machine is also fine.
Anyoner got any idea as to why this could be?
Tom

I don't know if this will help, I'm just wading into writing my own java apps to hit a SQL 2K db. We purchased a SQL2k/JSP driven backend on which we extended their OM to meet our needs. It was build as an extranet product but ran very poorly across the 'Net.
The biggest annoyance was not the actual transaction time of the app but the time it took from the end user to click a button and the start of the transaction.
After much testing I determined it was the JSP.
So what we have done to alieviate the issue is to have multiple regional Tomcats that 'throw' their transactions to a central colocation where the SQL servers sit (so the tomcats do the JSP managment in a sense locally to the end user) . For big clients we actually place a linux/tomcat box at the edge of their firewall. For whatever reason, I'm far too busy to determine the how now that I get the responses I need, this has completely eradicated the annoying pause between user interaction and the actual transaction to the DB server. Extended testing showed the SQL server running in the sub half second range to process a command but the tomcat rendering could take up to 2 to 5 seconds in worst case for no discernable reason. Moving the tomcat frontends to the network segment where the clients we solved it.
Of course I'm digging into swing now too and it has some slowness that the Eclipse zealots say SWT fixes but I haven't the depth or experience to properly judge the camps arguments yet.

Hello,
I am not an expert in MSDTC but as we know,SQL Azure Database does not support
distributed transactions. This means that SQL Azure doesn’t allow Microsoft Distributed Transaction Coordinator (MS DTC) to delegate distributed transaction handling.
One common cause of MSDTC getting involved in Entity Framework applications is the fact that we close and reopen the same connection as needed (i.e. for each query that is executed).To avoid the stack from opening and closing the connection multiple times,
you can simply open the connection explicitly and run the queries in the same connectio.
The following thread is about a similar issue, please refer to:
http://answers.flyppdevportal.com/categories/azure/sqlazure.aspx?ID=d705a8cf-cba4-494c-96f6-96a136bd29e3
What's more, you can also try the workaround that involves setting the Enlist option of the SQL Azure connection to false. For the detail explanation, please refer to:Entity
FrameWork and SQL Azure

I created a wireless network with my Time Capsule but would like to connect this network to a WiFi Hotspot for Internet Access

I have created a Wirelss Network at home with the Time Capsule and would like to connect this network to the Internet.
I can't use LAN Cable to connect to it anything becasuse I usually use the WiFi that runs through my building.
Can I connect the Time Capsule to the WiFi hotspot somehow so that all computers on my network have Internet access and if so, what do I need?
I need this done because the computers can only be connected to either the WiFi network or to my Time Capsule Network at any given time.
Or is there a way to be connected to both networks simultaneously?
I have two PC's and two Macs.
Thank you for any support and I apologise for my ignorance. I am not too good with networking.
I have tried the silliest of things like connecting a router to the TC only to then realise that the TC had an inbuilt router.
I tried connecting a USB WiFI adapter to the USB Port on the TC but it doesnt detect it that way apparently.
Please help!

I have a kinda same problem @ https://discussions.apple.com/thread/3531642
Please reply (somebody)!

Attempting to connect my MacBook to my 4s iPhone. I have had them connected in the past to use the "hand off" function. Today it tells me "network unavailable" make sure network access is enabled. I don't know what to do.

Attempting to connect my MacBook to my 4s iPhone. I have had them connected in the past to use the "hands off" function. Today it tells me "network unavailable" make sure network access is enabled. I don't know what to do. I love the hands off feature as my iPhone is never with me when on my mac! I'm not sure what to do. Both are "discoverable" via bluetooth and show up on each device but when I try to connect it says "network unavailable". HELP!

An iPhone will not pair via Bluetooth to a computer (Mac or Windows) except for personal hotspot and then only if your cellular plan supports it. https://discussions.apple.com/docs/DOC-7722
If you are attempting to use Handoff/Continuity, that does involve Bluetooth but the devices are NOT paired; Bluetooth just needs to be on and the devices in range of each other. The following may help with Handoff/Continuity issues: http://support.apple.com/kb/TS5458
